有隧道的长隧道挖掘无聊的机器(TBM ) 是一个复杂、随机的过程。在不同隧道节根据特定的地质的条件被调整被无常和需要容易影响,它使安排的构造和管理困难。基于岩石团分类,这份报纸估计穿入率。用率, TBM 无聊的系统的一个周期的网络模拟(气旋) 模型被建立,并且在不同地质的条件下面的进展率是坚定的。然后,工程安排上的不同切割器头戳的影响,根据以前的经验在合理范围被选择,被分析。而且,弄脏系统的模拟模型被造相当决定湿粪火车和栏杆交叉的数字,关于湿粪装载并且材料搬运的效率。基于在 TBM 无聊的系统和弄脏的系统之间的相互作用和相互关系,为全部通道过程的联合气旋模型被建立。然后合理的构造时间表,工作资源的利用率,和工程结束的概率通过模型编程被获得。最后,工程应用显示出介绍方法的可行性。
Long tunnel excavation with tunnel boring ily affected by uncertainties and needs to be adjusted machine (TBM) is a complex and stochastic process. It is eas- according to specific geological conditions in different tunnel sections, which makes the construction scheduling and management difficult. Based on the rock mass classification, this paper estimates the penetration rate. Using the rate, a cyclic network simulation (CYCLONE) model of TBM boring system is established, and the advance rates under different geological conditions are determined. Then, the impact of different cutter head thrust, which is chosen in reasonable range according to previous experiences, on pro- ject schedule is analyzed. Moreover, the simulation model of mucking system is built to determine the number of muck trains and rail intersections reasonably, regarding the efficiency of muck loading and material transporting. Based on the interaction and interrelation between TBM boring system and mucking system, the combined CY- CLONE model for the entire tunneling process is established. Then reasonable construction schedule, the utilization rate of working resources, and the probability of project completion are obtained through the model programming. At last, a project application shows the feasibility of the presented method.
